FAQs
What are SIP panels?
Structural insulated panels (SIPs) have a rigid PUR insulation core bonded between two OSB3 boards. Each panel is the structure, the insulation and the airtight layer in one. They're made to size in our workshop and go up fast.
Why choose SIPs over timber frame or brick and block?
They build faster (a frame can be up in as little as two days), insulate better, and create almost no waste on site. They can also save around 45% more CO₂ than stick-frame construction.
How well do SIP panels insulate?
Our 147mm wall panel achieves a U-value of 0.18, which meets current UK building regulations.
What do you supply?
Structural insulated panels (SIPs) have a rigid PUR insulation core bonded between two OSB3 boards. Each panel is the structure, the insulation and the airtight layer in one. They're made to size in our workshop and go up fast.
What sizes and thicknesses are available?
Our standard panels are 147mm for walls and 172mm for roofs. Send us your drawings if you need something different and we'll advise.
Can you cut panels for windows, bifold doors and rooflights?
Yes. Openings are cut to your drawings in the workshop. We can also make curved sections by cutting panels into thin strips and joining them with timber splines.
Do you dry-fit the panels before they leave?
Yes. We dry-fit panels in the workshop to catch problems before they reach your site.
How much do SIP panels cost?
Wall panels (147mm) start from £130 per m² and roof panels (172mm) from £150 per m², plus delivery and VAT. The final price depends on your design, openings and delivery location. Use our price calculator for an estimate.
How do I get a quote?
Send us your drawings, even a sketch with rough dimensions, and we'll come back with a clear quote, lead time and next steps. There's no obligation.
How do I pay?
We take a 50% deposit when you order and the remaining 50% before delivery.
How long does delivery take?
Do you deliver across the UK?
Yes, including Scotland and other remote areas. Delivery costs more for remote locations. We check access first, and arrange a crane or special equipment if needed.
How do I pay?
We take a 50% deposit when you order and the remaining 50% before delivery.
Do I need planning permission?
Yes, many customers do. We provide clear installation guidance and stay available for questions throughout. Tools you'll need include a nail gun, foam gun, crosscut saw, level, hammer, circular saw, hand saw and plane.
Do SIP buildings meet Building Regulations?
Not dry-fitting the panels first, which leads to fixing the wrong sections. The other common ones are bases that aren't level or square, and rushing the details around openings and junctions.
What certifications do you hold?
Yes. We help with design questions, cost-saving tips and planning, then support you through the install.
What warranty do you offer?
Our panels carry a 1-year warranty. Builds that meet Building Regulations can carry a 10-year warranty through the installing contractor.
Do you work with trade customers?
Yes. We supply builders, contractors, architects and homeowners.
Where are you based?
Pontrilas, Herefordshire.
